Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the datasheet for operating temperature ranges to guarantee reliability under expected environmental conditions.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The small 2.0x1.6 mm package is suitable for space-constrained designs. Consider the enable/disable feature if power efficiency during idle states is a priority. Verify that the 29.49 MHz frequency meets the exact timing needs of the target application without requiring external dividers or multipliers.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same physical footprint. The series provides standardized LVCMOS outputs for consistent integration across different product lines. The 'OE' suffix typically denotes specific operational characteristics or packaging variants defined by the manufacturer.

Oscillators Replacement Considerations

Direct substitutes must match the 29.49 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6 mm package. Check equivalent parts from other manufacturers for identical pinout and electrical parameters. Ensure thermal and mechanical specifications are compatible with the existing assembly process.
